.Application filed August 24, 1916. Serial a citizen of the United States of America,

county of Cook,

and a resident of Chicago,

invented certain and State of Illinois, have new and useful Improvements 1n of Collecting and Trucking Garbage, of which the following is a specification.

The main object of this invention is to provide an improved method of-treating and handling refuse material during the collection thereof from a number of successive stations. The improved device by which this method is to be carried out involves the use of improved means for treating garbage and the like at the time of collecting the same, so that no offensive odors will emanate from it while being hauled to the disposal station; improved means for crushing or grinding the garbage into fine particles so as to facilitate oxidation; improved means for drying the comminuted garbage as it is being stored in the collecting vehicle; and an which during the breaking up of the garbage will thoroughly mix the fine and pulverized particles of garbage with a current of air in such a manner that the garbage will be oxidizedto such a degree as to retard decomposition and precopending application,

vent fermentation except under extreme conditions.

An illustrative embodiment of the device by which this method is followed out is shown in the accompanying drawings, in which- I Fig. 1 is a side elevation partly in section of the improved vehicle, the of being broken away.

Fig. 2 is a sectional elevation of the garbage crushing device and a part of the lower rear end of the vehicle body.

eliminating the offensive odors, and making it possible for a comparatively large amount of garbage to be collected and transported to the disposal station in one of these vehicles. In the construction shown in the drawlngs, the motor vehicle 1 is provided with a body 2 which forms a storage compartment 3 for the garbage.

A garbage ing device 4 is mounted at the lower rear end of the body 2 and comprises a casing 5 within which a c linder 6 mounted on a shaft 7 is journaled in suitable bearings 8 and 9.

A plurality of hamme'rs 10 are swingwbly mounted in rows upon the outer surface 0 the cylinder 6 and cooperate with inwardly extending teeth 10.1 mounted on the interior of the casing 5, for crushing the garbage. The hammers 10 are of the usual type 11 1n garbage crushing machines and are mounted so as to have a flailing action on the material with which they come in contact.

A pair of shafts 11 and 12 are journaled sed able bearings on the casing 5, parallel to the shaft 7 which carries the cylinder 6. A plurality of disks 13 are rigidly mounted on each of the shafts 11 and be between the rows of cylinder hammers. Hammers 14:, similar to the cylinder hammers 10, are swingably mounted on the disks 13 and are space away slightl from the peripheral surface of the cylin er 6.

Rotation is imparted to the shafts 11 and 12 by means of gears 15 rigidly mounted on said shafts and which mesh with pinions a large gear 17 mounted on the cylinder 6. 6 is adapted to be rotated in a clockwise direction, (Fig. 2) and by means of intermediate pinions 16, the disks 13 carrying hammers 14 also rotate in a clockwise direction.

The rapidity and direction of rotation of hammers 14 with re to the rotation of cylinder 6 results in an air circulation around the cylinder'opposite to the directionof travel of the garbage. "A receiving chute 18 isprovided for receiving the arbage as it is being collected, and means %or normally closing the outer end of the chute are rovided and compr se a closure gate 19 rigi 12, said disks bey mounted on the in- The cylinder Y retained in close ner ends of a pair of arms 20, the outer ends of which are connected together by a transverse rod 21 which serves as a garbage can rest. The'arms 20 are pivotally mounted intermediate their ends so that when a garbage can-is placed upon the can rest 21 for the purpose of emptyin the contents into the chute, the weight 0 the can shifts the can rest 21 downward, thereby ra' ing the closure gate upward and uncoverin the end of the receiving chute so that the arbage from the can may enter the chute whi communicates with the crushin device. Upward movement of the gate 1s limited by a stop.19.l mounted on the casing 5.

A member 22 is disposed alon of the garbage receiving chute substantially underneath the cylinder6 and is mounted at its rear end on a transverse shaft 23. The

shaft 23. is mounted to rock so as to carry the member 22 downward away from the b cylinder 6, but the member 22 is normally proximity to the cylinder counterweight 24 slidably by means of a .mounted on an arm 25 secured to the shaft 23. The shaft 23 extends out through the cas ing 5 and has an arm 26 secured to its outwardly extending end which is connected to one arm of a bell crank lever27 by means of a connectin link 28. The other arm of the bell crank ever 27 is connected to a clutch 29 mounted on the cylinder shaft '7 and through which the cylinder is driven by means of sprocket wheel 30 over which runs a sprocket chain 31. The sprocket chain 31 is driven by a relatively large sprocket wheel 32 rotatably mounted on the rear axle of the motor vehlcle, which in turn is driven by suitable means 33 which havev connection with the motor of the vehicle.

The free end ofthe rockable member 22 'is provided with a plurality of small apertures 45 which are ada ted toactas outlots for the-pulverized gar age, and the extreme end of the member wardly at 34 and isspaced slightly away from the wall 35 ofa chute 36 which communicates with a conveyer 37 which surrounds the stor compartment 3. Suitable means are-provlded' for adjusti the size ofthe opening between the end 35 and comprise .a te 46 slidabl' mounted in the wall 35 amf provided wit a handscrew 47 for adjusting the same. I

The conveyer 37 is. of the type more fully shown and described in my aforesaid copending application, and is driven b suitable connections as shown anddescri my aforesaid application. The conveyer 37 is housed within a passageway 38, and said passageway is provided with a pivoted .door 39 at a point above the vice, so that material such asashes, which it is not desired to pass throu h the crushing device, may be poured direct y'into the con- 22 is bent downand wall garbage crushing de--- ve er passa wa and carried u to the tra doiirs 40 tl lfoug h which the garbage and other material is dropped.

. The exhaust pipe 41 from the motor of the vehicle extends back underneath the storage compartment 3, and theend 42 thereof extends upward and opens into the compartment 3 so that material which is being dumped into the compartment is subjecte to the hot gases of the motor and thereby dried.

Themotor gases exhausted into the compartment 3 come in' contact with the Walls of the compartment and are thereby condensed so that the oil therein trickles down the sides of the compartment and passes into vents 43 which have troughs 44 disposed thereunder for catching the oil and carrying it away to a suitable receptacle.

In the operation of the device, the garage can, as it isbein upon the bar 21, there y' orcin the bar down and raising the gate 19 whic uncovers the end of the chute. The stop-19.1 limits the upward movement of the gate and when the can is removed from thecan rest, the gate will resume its em tied, is rested gravity, thereby closing the gate of the chute W soas to preventthe escape of the obnoxious odors of the garbage.

' The cylinder is driven by'the motor of the vehicle throu h the chain and sprocket 33, sprocket 32, c 29, said clutch. being normally in engagement. As the garbage goes down the chute 18, it is subjected to the blows of the hammers 10. on the cylinder 6 and is broken" up into finely divided particles by the action of these hammers cooperating with the inwardly extending teeth 10.1, which are mounted on the interior surface of the casin 5. As the material is carried around the cylinder, it is also subject to the powerful blows of the hammers -14 driven by the shafts 11 and 12. The hammers 14 are rotatin in the opposite direction from that in w lch the garba e material is moving, strikes the garbage with extraordinary power.

Should any material'be :mixed with the ain 31, sprocket 30 and clutchand thereby.

garbage which cannot be'broken up by the crushing device, such material forces the rockable member 22 downwardly away from the cylinder and thereb aetuates thebell crank lever 27 through the arm 26 and link 28' so as to disengage the clutch 29, and thereby stop the-rotationfof thecylinder 6;

This automatic disconnectingofthe clutch- 29, whenmaterial which cannot be crushed is fed into the device, prevents the breaking or straining of the apparatus.

The garbage which is broken up into; fine particles drops down into the chute 36 through. the space between the end 34 of member .22 and the gate 46, and par-t'fof the pulverized garbage escapes through the apertures &5 into the chute 36. It is there picked up by the conveyor 37, carried up the passageway. 38 and dumped down through the trap doors 40. As it drops down through the doors 40 into the compartment 3, it is subjected to the hot gases from the motor and dried to such an extent that a large quantity of garbage can be stored in the vehicle.

. The size of the outlet between the gate 46 and the end 34 of member 22 may be ad justed to varying sizes by means of the handscrew 47.

The counterweight 24 may be adjusted along the arm 25 so as todetermine the weight necessary to rock the member 22 downwardly to unclutch the cylinder.

Although but one specific form of device for carrying out this method has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim a 1. The improved method-of collecting and trucking garbage, which consists in collecting the garbage at a plurality of residences, conveying the collected garbage from one residence to another in succession, an
